BOOKKEEPING-MACHINE.

Specification of Letters Patent. Application filed December 18, 1911.

T0 of! 'ziiiom it may concern."

. Be it known that I, GnsrAr EMANUEL Jmmxstm, a citizen of the Kingdom of Sweden, residing at Sundsvalh Sweden,

' I 5 have invented new and useful Improvements U). Boolcheeping-Machines, of which the following aspecification.

This in ention relates to Fniproven'ients in "the bookkeeping machines set forth in my application. Serial No. 584517,, filed Septen'iher iinh 1910, the object of the pres- ,ent intention being to simplify the construction and operation of said machines.

The invention consists chiefly in that the sectionsis or are arranged to be operated directly by the 'etting section, this being adv-. intage nis innuch as all subdivisions of the account tion maybe exactlyof one and the sanie. ln usingonly one checking sectioirthis.uiaybebuilt together with or connected to the setting section whereby the .use of the machine will be essentially sim- I Ipliited.

f In the accom jianying drawings I have shown one embodiment of my invention. Figure tshows a cross-section on. line -,i\-.l in Fig. 4 and partly an end view of 1 the Imichine. Fig. 2 shows a cross-section in Fig. 1 and partly an end view of the machine. Figs 3 and 4 show longitudinal sections of the checking tion, with the gears-in difi'erent positions.

and (i show on a larger scale details, ofthe CllCUiiUl section in ditlercnt iosit-ions. i a

"Figs. 7 and show likewise. in a larger scalc detail viewsoit the gear-inesof the checking section in different positions.

In the drawings I have shown only thoseparts of the machine that are nccessarv to llustrate the present invention. All parts that have already been described in my beprior application are indicated bythe same reference characters as in saidlapplieation Among other features my novel machine comprises a checking section each toothed wheel. 10 of which operates one pair of toothed wheels 16, 16 rotatably mounted on an axle 17 which is movable longitudinally.

When the setting section is placed in posia. subdivision of p 1 section, one sixteenth of the wheels of each pair of wheels 16, 16 comes into engageof a series of toothed wheels C .57 in said subdirision. These toothed wheels the accountvaccount section.

16 is transmitted to the Patented Nov. 5, 1912. Serial No. 666,594.

57 operate by means of intermediate wheels.

28 the toothed wheels 56 which are secured to the figure wheels 51. The other wheel 16 of each pair of wheels 16, 16 are in the form shown in the drawing in engagement with toothed wheel 78 of the corresponding figure wheel 79 of the checking section. All axles 5, 6, 7, 8 and 9 are journaled in the walls 11 and 12 of the setting section. In as much as the toothed wheels 1 always are operated in one and the same direction by the toothed wheels 16 the gearings between the toothed wheel 2 and the figure wheels 79 mustbe reversible, so that the direction of rotation of said figure wheels can be changed, according as a debit or credititem is to be recorded in the machine. For-this purpose the shafts 6 and T in the form showi'i are movable longitudinally and rigidly secured to each other by meaens of a cross piece 14 which is actuated by a, spring 15 tending to keep the two shafts 6 and 7 in the oii-e end position. In the other direction the said cross piece let is actuated by means of an angle lever 18 pivoted to the wall 12 and having at one end a pin 19 which bears against said cross piece, while the other end of the lever 18 carries a roller 20 which bears on a strip 21 provided on the Each of the wheels Qhas two rings of teeth separated by an annular groove 22 .of at least thesame depth as the height ot the teeth. while the width of the teeth of the wheels 1 is somewhat smaller than the width ofthe grooves 22. In position of the shafts (3 and 7 (Figs. 3 and the toothed wheels 1 are. placed opposite the grooves 22 of the-wheels 2,v in which case the movement of the toothed wheels 15 is transmitted to the figure wheels 79 or the toothed wheels. 78 thereof by 111021115 ot the toothed wheels 1. 3 and In the other position of the shafts (5 and 7 (Figs. land 6) each. toothed wheel 1 enga teeth of the correspondii1g 2, while the toothed wheels :5 artv brought out of engagement witlrthe wheeig .1. in this case thenmvement of the toothed wheels figure wheels 79 or the toothedwheels 78 thereof by means of the toothed wheels 1,2. ,3 and i so that the figure wheels 79 are rotated in a direction opposite to that. in which they were rotated in the torn or case. The reversal of the direction. of rotation of the figure wheels Tl) ges one 'ring of toothed wheel is accomplished automatically incidental to the placing of thesetting section in position opposite a subdivision of the account section corresponding for instance to the debit of an account, when the roller 20 of the angle lever 18 runs down into a recess 23- of the strip 21, as is shown in Fig. 3, and the spring 15 displaces the axles 6 and 7 from the position shown in Figs. 4c and 6 to the position shown in Figs. 3 and 5. As soon as the roller 20 runs up from a recess 23, the angle lever pulls back the shafts 6 and 7 into the position shown in Figs. 4 and 6. Recesses 23 are provided only for'such subdivisions of the account section as correspond to the debit of the accounts or only for such subdivisions as correspond to the credit of the accounts. a

In order that the checking system may be used in making additions or subtractions by means of the addition and subtraction section shown in the before mentioned application the. checking section must be provided with means allowing it to be adjusted manually for addition and subtraction. This adjustment however should not be possible until the checking section has been placed in position opposite the said addition and subtraction section. For this purpose the following arrangement is made. In the checkl ing section is journaled an axle 25 having a crank 2i and two lateral projections 26 which bear on or are in close proximity o the strip 21 thereby preventing the axle 25 from being turned by means of the crank 24. The strip 21 does not extend over the sai addition and subtraction section, and therefore the axle 25 can be turned by means of the crank 2% when the checking section has been placed in position opposite the addition and subtraction section. The angle lever 18 has a pin 27 which in the position 0 the crank 24 shown in Figs. 2 and 8 bears on an eccentrlo surface at the inner end of the axle 25. WVhen the crank 2 l'is turned into the position shown in Fig. '7, the said pin 27 is raised 'by the axle 25,as is evident i from Fig. 7, whereby the angle lever 18 is caused to displace the axles 6 and 7 in the same manner as when the roller 20 runs up from a recess 23. As long as the checking section stands opposite the addition and subtraction section, it is thus possible to adjust the checking section for addition or subtraction at will by means of the crank. 24. If the latter when the checking section is moved back to the subdivisions of the account section to the position shown in Fig. 7 the projection 26 .of the axle 25 will strike sition opposite the end of the strip Fig. 7, whereupon it will cause the cran to be turned into the position shown in Fig. 8, in which the axle 25 is kept locked until the checking section. again is placed'in posection.

Instead ofbeing arranged in the setting section the checking section may be made as a separate part of the machine which may the account section. For adjusting the checking section automatically from addition to subtraction and vice versa any arbitrary means may described for section from addition to subtraction and vice versa any other suitable means may be substituted. If desired one may, as described in my before mentioned application, provide two or more which case the means for automatically adjusting-said sections from addition to subtraction may be dispensed with, in as much as in this case one checkin section may be arranged to record all debit items and an- 85 other all credit items.

-Having now described my I claim as new and desire to secure by ters Patent is.

1. A book-keeping checking section, a setting se tion and an account section; the checking section being operable directly by the setting section, an means for automatically adjusting the checking section from addition tion and vice versa according as same is placed opposite a subdivision of the account section corresponding to the debit or credit of an account.

2. A book-keeping checking section, and a setting section; the checking section being operable directly by the setting section and being provided with means for adjusting it manually from addition to subtraction and vice versa, and locking mechanism constructed to prevent invention, what Letthe checking section from being adjuste manually from addition to subtraction and vice versa until said section is placed in a certain position.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
